Issue 7 of Photochemical & Photochemical Sciences is a themed issue on ‘Blue-light photoreceptors’ and is now available to read online.
The front cover this month features work by Aba Losi and co-workers from Parma, Italy. Their article takes as its starting point the increasing evidence that prokaryotic organisms can sense and react to light stimuli via a variety of photosensory receptors and signal transduction pathways. The authors present a comprehensive scenario of the existence of bilin-GAF, LOV and BLUF proteins in the prokaryotic world, and inspect possible phylogenetic pathways. They also define novel criteria for identifying gene (and protein) sequences based on experimentally assessed photochemical events.
